Mnemonic Program Editing
The mnemonic view of a program allows mnemonic instructions to be typed directly. This feature is for
advanced users who wish to bypass the more structured programming available in the Ladder program.
Select the
View Mnemonics
button from the toolbar. The Mnemonics view is displayed in the
Diagram Workspace.
Whenever mnemonic instructions are entered, the Ladder program of the program is updated. When a complete
rung has been formed by the entered mnemonics, CX-Programmer normalises the new mnemonics and redraws
the rung.
It is possible that during the entry of the mnemonics, the rung can not be drawn in ladder form. In this case, it is
shown as a statement list box on the Ladder program.
In order to enter a comment for a rung into the Mnemonics view, enter the character ‘`’ followed by the text.
This type of comment must go at the start of a rung’s mnemonics.
In order to enter a comment against a ladder element, enter a comment statement following it - enter the
characters ‘//’ followed by the text.
In order to enter a rung annotation (unattached comment), enter the instruction type ‘A’ followed by the text.
This type of comment must be at the end of a rung’s mnemonics.
Working On-line
CX-Programmer permits the connection of the PLC to the computer through the project, and
subsequent additional features once the PLC is ‘on-line. Select the Work On-line button from
the toolbar to connect to the PLC.
Auto Online to a PLC
When maintaining a PLC, CX-Programmer can start monitoring the program of the connected PLC with a
toolbar button, after CX-Programmer is started. A PC must be connected to a PLC.
Use the following procedure to go on-line to the PLC automatically.
1, 2, 3…
1. Select
the
Auto Online
button from the toolbar. A dialogue is displayed showing the
PLC type and the network settings of the connected PLC, which CX-Programmer is
searching. When CX-Programmer successfully finds the PLC information, it
automatically goes on-line and transfers all the data from the PLC, for example,
programs, expansion function (if available), PLC settings, IO table (if available), symbol
tables and comments.
2. Select
the
Select Serial Port
option from the PLC Auto Online menu to change the serial
port when Auto Online. The default serial port is set to COM1.
Work Online to a Simulator
A program can be monitored or debugged by using a simulator rather than connecting to a PLC.
Use the following procedure to go on-line to a simulator.
